I have never hunted deer with a shotgun or ever used slugs so I need some info. But now I am going to deer hunt a place that only allows shotguns so I need help. I have a Pardner Single Shot 12 gauge and the barrell says 3". Would this gun be worth trying to use? If so, Can you guys give me some info on what I would need to get to use this gun? Or would it be better if I just spent about $150 and got a Mossberg Maverick 88?
